Repy unit tests do not run correctly with python 2.7

[choksi81]

On Ubuntu 11.04, x86_64, Repy unit tests that pass on python2.6 fail with python2.7.1. This is true as of r4983.
Output is attached.

This does not appear to be an issue on Windows or Mac.

It appears that the cause of the problem is because threading.py was modified to call hasattr, which is not allowed by repy, in _after_fork(). This is line 852 in Python2.6, and 866 in python2.7

After commenting out lines 888 and 889 from python2.7's threading.py

if hasattr(thread, '_reset_internal_locks'):
    thread._reset_internal_locks()

the code runs properly on python2.7, on linux.

Fixed in r4986.

The problem exists for RepyV1 unit tests, too; the fix is the same. I'm backporting it.
